Breakdown the Primary Series of Astanga  

The goal of this workshop is to demystify Ashtanga Primary Series postures for those new to the series as well as experienced Ashtanga practitioners looking for a fresh perspective.

Saturday, April 25th in Cambridge with Lynne from 1:30-3:30.  Register here.

Join Devon for this in-depth practice that expands upon the weekly prenatal class.  Breathing techniques and a guided meditation will follow our asana practice. Bring a partner, spouse or a buddy. Appropriate for all levels and all trimesters of pregnancy.

Astanga 2nd Series  

Join Elliott & Lynne and practice the Second Series of aṣtanga yoga. This practice builds on the work in our regular Primary Series classes, but focuses more on backbending and hip opening, with some fun inversions, dynamic jumping postures, and of course the 7 headstands. Second Series classes are held on the final week of the month, in place of the regular aṣtanga classes at those times.  Check the schedule here for more info. Cambridge and Somerville!

Weekly Meditation in Cambridge  

Like yoga, no one is “bad” at mediation. You do by practice! Join Karen “Shanti” Caiazzo Thursday nights at 6:30 pm for a 30-minute sit. We will practice breathing techniques, mantra, and open-eye meditation.   Appropriate for beginners and seasoned meditators.
